Description

Allen-Bradley 1756-L73 is one of the ControlLogix series controllers produced by Rockwell Automation.The following is a detailed introduction to the controller:

1.Basic attributes

Brand:Allen-Bradley(AB for short)

Model:1756-L73

Series:ControlLogix

Type:Programmable Automation Controller(PAC)

2.Hardware features

Processor:Logix 5573 processor,providing high-performance control capabilities.

Memory:

User memory:8MB,used to store user programs and data.

I/O memory:0.98MB,used to store I/O configuration information.

I/O capabilities:

Can connect up to 128,000 input and output signals,and 4,000 analog input and output signals.

Allen-Bradley 1756-L73

Supports local I/O configuration(I/O modules are installed in the same chassis as the controller)and distributed I/O topology(expansion I/O is installed away from the processor and provides I/O through an expansion communication bus).

Communication interface:

Supports modern communication protocols such as Ethernet I/P,DeviceNet,ControlNet,Synchlink,etc.

Compatible with traditional communication protocols such as Data Highway Plus(DH+),Remote I/O(RIO),and third-party protocols.

Configurable to communicate with gateways and protocol converters.

Other features:

Integrated motion function,supports motion control on SERCOS interface,analog motion sensor,and Ethernet I/P.

Equipped with energy storage technology,no battery is required to retain the contents of volatile memory.
